@lhara15 Hey, if you right-click the game in Origin, it should hopefully revert the patch install and get you playing again. If it doesn't, uninstall, run ccleaner, then reinstall through Origin.

If any DLC isn't present that should be, be sure to check on the BSN DLC page: https://social.bioware.com/user_entitlements.php
